FALL AND COCKKRELL. 257 



IVIordellistena divisa Lee. 



A specimen taken at Pecos by Prof. Cockerell seems to fit Le 

 Conte's description, differing from the eastern inarginalis by its 

 more abundant paler yellowisii pubescence as indicated by LeConte. 

 I find also that the antennae are much stouter than in marginalis, 

 the outer joints being but little longer than wide, while in margina- 

 lis — as represented by examples from Ohio — they are nearly or quite 

 twice as long as wide. If the Pecos specimen is really clivisa, as 

 seems very probable, the validity of the species is unquestionable. 



MELOID^E. 



Zoiiitis martini n. sp. — Piceous, thorax red, with a small faint central 

 dark spot; surface feebly shining and with very short, fine, recumbent, pale 

 pubescence. Head less elongate than in atripennis, the mandibles less prolonged ; 

 epistoma and front of labriim pale; tempora parallel, front and vertex densely 

 not coarsely punctate, occiput more sjjarsely punctate. Eyes large, distant on the 

 front by baiely twice the length of the second antennal joint, beneath by veiy 

 slightly more than the length of tliis joint. Antennte slender, setaceous, moie 

 than three-fourths the length of the body, second joint three-fourths the length 

 of the third, joints 3-10 subequal, three times as long as wide or a little less, ter- 

 minal joint a little longer. Protborax equal in width to the head, slightly more 

 than three-fourths as long as wide, sides parallel in basal half, rounded and con- 

 vergent in front, apex but little more than half the width of the base; surface 

 strongly and moderately closely punctate, the punctures somewhat unevenly 

 disposed, but separated as a rule by less than their own diameters; median line 

 finely but distinctly sulcate posteriorly. Elytra densely punctate, the punctures 

 of moderate size and closely crowded. Spurs of hind tibiae equal, rather slender 

 and acute. Length 8 mm. 



Engle, New Mexico. A single specimen collected by Miss Nora 

 Newberry and sent me by Prof. Cockerell. A second specimen 

 collected by Master Martin D. Cockerell at Mesilla Park on mes- 

 quite is in the National Museum collection. It gives me pleasuie to 

 dedicate the species to its original discoverer. The type is a male, 

 having the fifth ventral segment broadly triangularly emarginate. 

 It is a true Zonitis, the maxillary process being undeveloped. 



ZonitiK vigilans n. sp.— Yellow, elytra brownish, metasteruum, tibia' 

 and tarsi dusky; pubescence pale, short, sparse and moderately inclined. Head 

 of the usual elongate form, the tempora scarcely diverging, surface closely punc- 

 tate, a small smooth callus between the eyes. Eyes very large, separated on the 

 front by a distance equal to their own vertical diameter, beneath by a distance 

 rather less than the length of the second antennal joint. Anteunaj three-fourths 

 the length of the body, slender, setaceous, second joint three-fourths the length 

 of the third, intermediate joints parallel and about four times as long as wide.
